-j IMPRovEt/IENT 1N WHEELED HARROWS.

To all whomfit 'ma/3j concern:

Be it known that I, A. L. P. VAIRIN, ofBipley, in the conntypof Tippah,and State of Mississippi, have' invented a new and-improvedWheel-Harrow; and I do hereby declare that the following is afull,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specication.

This invention relates ,to hai'rows, and consists in the constructionand arrangement of parts, as hereinafter specified; p Y y Figure lrepresents a side elevation of my improved barrow, part-ly brokenout-and 4 Figure 2 represents a plan vien' of the same.

Similar letters of reference indicate corresponding parts.

I mount a shaft, B,on any suitable frame, A, pro-A vided with a tongueand a seat, the said shaft being for the reception of the revolvingdisks C, cast, or otherwise formed with hubs, having holes for theshaft, and of suicient length to Ycause the disks to be separated asmuch as required.

This shaft is bent at the centre, as represented in fig. 1, so that theplanes of the disks will not be parallel with the line of the draught.The said disks may he plane, or concave-convex, as required, and beingused as rollers Whereon the frame is drawn along the ground, they willbe pressed into it by the weight of the frame, and will cut and turn itup, more or less, according to the inclination from the line of draught,and the measure of their dip or dishing shape.

The Schedule referred to in these Letters Patent and making part ot thesameA Scrapers VF are arranged near thev faces of the disks, by whichthe latter turn upward at the rear, to insure the delivery of the earth.

This apparatus serves excellently for. pulverizing or cutting up weeds,grass, and other matters on thesurface. When used for th'e latterpurpose, the disks should be flat and sharp, and set only a little outof the line of draught; but when used for pulverizing, they should havea greater inclination, and. should also be (lished. The more dish, andthe greater Ainclination the disks have, the greater will oe the power'required to propel the machine, but the pulverizing effec-t will beincreased in the same measure,

The shaft may be made in two parts, and arranged so as to be adjusted tovary the inclination; and they may also be arranged so that the disksmay be readily removed for the substitution of others.

The shafts may extend outward, beyond the frame,

for the application of truck-Wheels ofA larger diameterl than the disks,lfor transporting the barrow.

Having thus described my invention, I claim' as new, and desire tosecure by Letters Paf/- 'ent- In combination with the frame A, thedisk'sB, arranged to rotate on the laxle B, bent at its centre, allconstructed as shownand described.
